Prevalence of Publication Bias Tests in Speech, Language, and Hearing Research.

Purpose: The purpose of this research note is to systematically document the extent that researchers who publish in American Speech-Language-Hearing Association (ASHA) journals search for and include unpublished literature in their meta-analyses and test for publication bias.

Method: This research note searched all ASHA peer-reviewed journals for published meta-analyses and reviewed all qualifying articles for characteristics related to the acknowledgment and assessment of publication bias.

Results: Of meta-analyses published in ASHA journals, 75% discuss publication in some form; however, less than 50% test for publication bias. Further, only 38% (n = 11) interpreted the findings of these tests.

Conclusion: Findings reveal that more attention is needed to the presence and impact of publication bias. This research note concludes with 5 recommendations for addressing publication bias.
